To QM "whom it may concern.-

Bc it known that 1, JOHN B. GORDON, a citizen of the United States of America, and resident of Meridian, in the county of Lauderdale and State of Mississipi, have invented certain new and useful improvements in Excavating hlachi nes, of which the following is a specification.

he invention relates to that class of machine adapted to dig a trench and to throw the dirt to a great distance, and more particularly it re ates to the buckets used for such machines.

/Vithout defining the various scopes of noveity, which are attended to in the claims, the general nature of the invention coniprises parailel hooks, sleeves separating the same, bolts passing through said hooks and said sleeves, sheet metal connecting said hooks and bent to form a bucket, turningplows on the end hooks, cultivator-points on the intermediate hooks, and guards extending from the shanks of said hooks and bent toward the points 01"" said hooks.

Figure 1 a side elevation of the machine. Dotted lines represent hidden parts or else parts that are behihd other parts. The essential parts which are omitted for the, sake of clearness-in one of the figures are shown'in some of the other figures. the ins-chine. -Figs. 3 and 4 are different views of the construction of one of the buckets.

The machine consists of a platform 1, having lateral extensions 2 and 3, the former carryirg the boiler 4 and the latter the standaros 5 with their braces 6.

The standards 5 are provided at the top with bearings 7, supporting the shaft 8, upon which axially mounted a three-section hexagonal drum 9. The smaller or lateral sections a! crowded Wlilll sprockets to atford a tonal grip to the endless excavat- Journaled upon the shaft 8 and nding therefroi'n are two carrier-bars 11, coir, ig journaled in their lower ends a shaft 8, incl ntcd upon which is a three-section d min f) similar'to the upper ones.

i ivotally connected to the carrier-bars 11 by means of a shaft 12 are two thrust-bars it), provided upon their under sides with racks I i, meshing with pinions 15, mounted journaled in bearings 17. A rotation of the shaft 16 thus advances or retracts the lower hexagonal drum and when rotating to the left thrusts same forward and upward and when rotating Fig. 2 is a plan of I to l ing-gears 62.63,'64,a-.n'd 65 "crowd of n,

the right backward and downward. By these means the depth of excavation is varied. The inner end of the shaft 16 is provided with a miter-gear 18, meshing with another 19, mounted upon a shaft 20 at right angles to the shaft 16, and provided with bearings 21 and 22. In the rear, mounted upon the platform, are standards 23, carrying upon their upper extremities box like bearings 24, open at both ends and through which are adapt-ed to travel the carrier-bars 25, having journaled in their outer ends the shafts 26 of the rollers 27, over which passes the endless conveyor-belt 28. Upon the upper faces of the bars are fastened racks 29, meshing with the pinions 30, mounted upon the shaft 31 in the bearings 32, which are rigidly attached to the box-like frames 24.. Upon the inner end of the shaft 31 is mounted a sprocket 33, driven by means of a chain 34 and the sprocket 35, mounted upon the shaft 36, journaled in bearings 37 38, the shaft carrying at its other extremity the mitor-gear 39.

When the shaft 31 is rotated in one direction or the other, the carrier-bars 25, carrying the rollers -17 with their endless belt 28, are carried bodily to one side or the other and project to a greater or less extent beyond the sides of the platform 1, so as to deliver the excavated material to any desired position.

Exterior to the carrier-bars 25 and mounted u on the shafts 26 are two sprocketwhee s 40, surrounding which is an endless chaindl, which causes both to rotate in unison when same is driven by the sprocketwheel 41, which meshes with the chain -11 and is mounted upon the shaft 43. The sprocket-wheel 42 on shaft 43 is driven by the chain 45 from the sprocket-w heel 46 upon the shaft 47 in its bearings 48 49 and other end of the shaft having the miter-gear 50 attached thereto.

The engine 51 is reversible and may be of any approved construction. It is provided with a pinion 52, which meshes with a large gear wheel 53, through the medium of which the shaft 54 is driven. The shaft 54 is sup ported in bearings 55 and is provided with a clutch 56 to engage or disengage the sprocketwheel 57, which drives the excavator-shaft 8 through the medium of the chain 55 and the s rocket-wheel 59 upon the shall 5%. The cliltch 56 is operated by means of the lever 60.

Mounted upon the shaft. 5; are the iii) the shaft 66, which is journaled'in the bear ings- 93 94.

5 The excavator-buckets which form the miter-gears with shifter between and operating the shifts 20, 47, 66, and 36, respectively, through the medium of the miter-gears 61, 50 67 and 39. Each reversing-gear is operated by means of a lever 69. At the rear the macaused to lock one or other of them upon the shaft. Immediately below these gears are others 78 79 80 in mesh with them and mounted upon a short shaft carrying a sprocket-wheel 81, over which passes the chain 82 to the rear of the machine and over the idler 83. By this means the machine may be propelled fast or slowly.

Steering is attained by means of the front wheels 84, mounted upon a swiveling frame '85 and. provided with a flanged circular upper pcrt-ion 86, to which is attached the chain 87,

which at opposite ends is wrapped over and.

rider the shaft 88, a rotation of the latter one way or the other causing the machine to travel to one side or the other.

The swiveling frame is supported on the bracket 89. The shaft 88 is journaled in bearings 90 and provided withljchemiter-gear 91, which meshes with the miter g'ear 92.11pon endless excavatingand elevating belt are in detail as follows: They are formed by a number of fiat sections of metal 95, laid parallel and held in that relation by means of rods 96 passing through all of them and having sleeves 97 between each pair.

The lower ends of the pieces are curved to form hook-supports and are linedwith sheet metal 98, as also are the ends, so as to form a trough or bucket. The hooks 95 extend beyond the trough portion and all of them except the two outer ones are provided with cultivator-points 92. The two outer ones have short turning-plows 100attached. There is a guard 101 in front of each cultivatorpoint having a rearwardly-curved point 102, whereby the buckets are enabled to jump over any obstruction too hard to cut through. The hooks are thin to cut through the dirt easily to break it up for the buckets. Each piece 95 is attached to the next one above and below by means of links 103. The dirt is picked up by the buckets 98 and dumped upon the conveyor-belt 28, which isadjusted, as before described, to drop. the dirt at differ-- ent distances laterally of the machine.
